The article discusses the structure of the system for transmitting and receiving dispatcher commands to mine personnel using a wireless electromagnetic channel through rocks to a depth of 1000 m in the frequency range of 0.3-30 kHz. The methods of modulation and coding of information in the channel are considered taking into account man-made noise.
